You must always stop after a collision, no matter how minor the collision may seem. Failure to stop is an offence and could even result in a prison sentence. Call 999 if you or anyone else has been injured. 

At the scene collect as much information as you can, including photographs, sketches of the vehicle positions and notes. Some useful information to note down would be: 

• Date, time of day, location, weather conditions, traffic conditions, any road markings or signs. 
• The vehicle make, model, registration number, condition, colour, estimated speed, direction, use of lights and indicators, and number of passengers. 
• Details about the driver, including contact information and a description. 
• Make a note of any witnesses, including passengers, onlookers or police officers, and if possible get their contact details too. 
• Make a note of any damage to the vehicles or to any property, as well as any injuries caused.   

Give your details to anyone else involved. If anyone is injured, It is essential that you provide your insurance details. 

• This means swapping your name and address with someone you may have crashed into, or leaving your details on the windscreen of a parked car that you may have hit. Even if no one has been injured, swapping details can be useful as it may help to speed up the claims process. 
• Avoid saying sorry or taking any blame for the accident until you know exactly what happened, as this could affect the claim further down the line.
